RDTIHY DRESSING IMPLEMENT.

Patented June 11, 1907.

Application tiled August 4, 1905. Serial No. 272,770,

To all whom t may concern.-

Beit known that I CHARLES E. CAMPBELL, a citizen of the Unitedl States, residing iin Lynn, in the county of EssexI and State `of Massachusetts, have invented an Improvement in Rotary Dressing Implements, of' which the following description, in connection with the accompanying drawings, is a s'peciieation, like letters on the drawings representing like parts.

The present invention relates to a rotary dressing implement, and is Shown as enibodied in animplement adapted for applying tion being to produce an iniplement partly :mechanical and partly manipulated by hand so as to combine the advantages of a mav chine with the advantages of hand manipulation.

To these ends, the implement embodying the invention comprises an ap lying member or brush, as it will be hereina ter referred to, combined with a motor of any suitable or usual kind for producing a rotary movement of the brush, and a flexible driving connection between the motor and the brush so that the latter can be moved about upon the leather, or other material which is being dressed, and the pressure and length of time oit-application to any one part of the material intelligently regulated bythe operator. The brush is further arranged to be sup )lied with liquid through a iiexible tube, an the supply ot' liquid may be controlled by a valve operated many suitable or usual way.

Figure l is an elevation of an implement embodying the invention, the brush portion being shown on an enlarged relative scale, I and in vertical section; and Fig. 2 .is a sectional view of the brush portion showing a modification.

The brush a, is herein shown as a disk of felt, or similar material, 'capable of being saturated with liquid, such as dressing for leather, and is arranged to be rotated mechanically,as by an electro-motor A. In order that the brush, While rotating, may be moved over the surfaceto which the liquid is applied, and sldllfully manipulated so far as relates to pressure and length of time ern loyed in treating any one part of the surace, the said brush is connectedwith the shaft of the motor by means of a flexible shaft c which may be of any suitable or usual construction. At the saine time, the brush c is supplied With liquid through aiexible pipe `vided With a finger piece or b 'from a reservoir B, there being a cut-off to control the supply.

In the construction shown in Fi l, the rotary brush is mounted in suitable earings in a handle portion c, the brush proper being connected with a bearing member a? shown as having'a conical portion a4 arranged to bear upon' anti-friction balls 'c5 contained in ball races c2 formed in the handle portion. The bearin f portion cS'is directly connected with a soli shaft a which rojects through the handle member c, the brush and shaft being maintained in position by means of a collar a7 secured to the shaft as by a set screw as, the handle portion c being shown'as provided with a hardened washer c3 for the collar a7 to bear upon. The handle portion c is further provided with a casing c4 which in closes the brush proper c, the s ace within the said casing forming a cham er c5 to receive the liquid or dressing which is to be applied to the material. The lem'ble pipe b 'opens into the said casing, the supply of liquid being controlled in this construction by means of a valve b2, herein shown as a cutoff member provided with an opening b3, the said member being movable transversely across the tubular portion c" of the member c4 with which the flexible i e b is connected, and being normally hel closed by means of a spring b4. In the drawing, lthe valve is shown as open, the valve roper being proof which the valve may be opened at the Will of the operator. In order that the liquid may be quickly applied to the surfaceY of the material under treatment, the brush a in this construction is shown as rovided With orts or openings a leading directly throng the brush from the chamber, so that the 1i uid will flow through as soon as the valve 2 is opened.

While the controlling valve b2l is a practicable expedient, it may, in some cases, be desirable, when liquid is used, to regulate the flow thereof in other ways, and, in Fig. 2, a modiiied construction is shown in which the supply of liquid is controlled by pressure upon the handle c, the said handle and the brush bein movable with relation to each other. As s own in Fig. 2, the handle ortion c is provided with an annular channel)c" o en at the bottom, and in communication at t e top with the tube b. The said channel fits, ap

lproximately, in an annular opening formed in the top of the rotating member am which,

iob bi by means ICO los

TIO

inthis case, instead 'of being directly connected With the brush a, is separate therefrom7 but arranged to bebrought into connection With the `brush by pressure upon the handle c. The liquid supplying chamber ci, in this case, is formed by providing the brush holding portion 0,30 `with an upwardly vprojecting flange 1,40 Which fits around the disk portion of the rotating member el, there being a spring a41 interposed between the top of the brush member and. the said disk portion. The brush, in vthis case7 is held in position by means of an annular collar L42 shown as screwed upon the outside of the ila-nge am, so as to Voverlie the disk/portion of the driving member.r Projecting upward from the top of the brush-holding portionA L39 is an engaging member L43 arranged to tit a corresponding recess in the disk portion of the driydn'g member, the said recess being below the liquid supplying channel c and provided with openings for the iioW of liquid into the chamber 050.. When the brush a isin contact With the material, pressure upon the handle portion c'will force the. driving portion al" and the brush holding portion into contact, thus causing the brush c to rotate 4with the driving portion,l and, at the same. time,

cutting. ofi' the supply of liquid by closing the openings through thedriving portion. The disk which supports the brush is shown as provided With openings a, the brush itself, in this case, being shown as a solid mass of felt through which the liquid permeates,

eeaeeo there being no direct openings through it, a in the construction shown in Fig. 1.

What I claim is:

1 A rotary dressing implement comprising a rotary brush; a motor; a eXible drivin' connection between said motor and sai brush va casing for said brush; and means for supplying said casing With dressing material.

' 2, The combination With a rotary brush;

of a motor; a flexible shaft directly connected with said motor and said brush; a sourceof liquid; and a flexible tube leading from said source to said brush. y 3. The combination with a rotary brush; of a handle constituting a bearing therefor; a chamber' formed in said handle to receive dressing material; a lexible'driving shaft connected with said brush; and means' for vsupplying said chamber With dressing material.

4. The combination With a rotary brush; of a handle constituting a bearing therefor; a chamber formed in said handle to receive dressing material; a flexible driving shaft connected With said brush a reservoir. for dressing material; and from said reservoir to said chamber.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing Witnesses.
